ΛN and Ξ N Interactions Studied with Lattice QCD
EPJ Web of Conferences, 2010 We present our recent studies of Lambda-Nucleon (ΛN) as well as Cascade-Nucleon (ΞN) interactions by using lattice QCD. The equal-time Bethe-Salpeter (BS) amplitude of the lowest energy scattering state of baryon number B = 2 system (proton-Λ and ...

Strong-Isospin-Breaking Correction to the Muon Anomalous Magnetic Moment from Lattice QCD at the Physical Point. [PDF]
Physical Review Letters, 2017 All lattice-QCD calculations of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment to date have been performed with degenerate up- and down-quark masses. Here we calculate directly the strong-isospin-breaking correction

Berry Phase in Lattice QCD [PDF]
Physical Review Letters, 2016 We propose the lattice QCD calculation of the Berry phase which is defined by the ground state of a single fermion. We perform the ground-state projection of a single-fermion propagator, construct the Berry link variable on a momentum-space lattice, and calculate the Berry phase. As the first application, the first Chern number of the (2+1)-dimensional

RECENT PROGRESS IN LATTICE QCD [PDF]
International Journal of Modern Physics A, 2009 In recent years, realistic unquenched QCD simulations have been carried out with various lattice actions. In this report, I explain the progress in theory and algorithms and some of the physics results.

QCD ON A TRANSVERSE LATTICE [PDF]
Particle Physics Phenomenology, 2001 We present results from a transverse lattice study of low lying mesons. Special emphasis is put on the issue of Lorentz invariant energy-momentum dispersion relations for these mesons. The light-cone wave function for the $ $ obtained in this framework is very close to its asymptotic shape.

Advanced Science, Volume 11, Issue 7, February 16, 2024.A new type of photodetector based on PG system (TaSe4)2I is proposed, and high photo responsivity covering ultrabroadband wavelength range (UV to LWIR) including mechanism are revealed in proof‐of‐concept nanoribbon devices. The achieved photodetection performance is superior than most of other low‐dimensional materials.

Lattice QCD study of the χc1→J/ψγ decay
Physics Letters BWe present the results of our lattice QCD computation of the electric (E1) and magnetic (M2) form factors relevant to the χc1→J/ψγ decay by using the gauge field configurations produced by the Extended Twisted Mass Collaboration with Nf=2+1+1 dynamical ...

Spectroscopy of Pentaquark Baryons
, 2005 A review is given to pentaquark mass predictions in quark models and QCD. It is pointed out that no successful quark model prediction is available for low-lying pentaquark states.

Constructing and Machine Learning Calabi‐Yau Five‐Folds
Fortschritte der Physik, Volume 72, Issue 2, February 2024.Abstract Motivated by their role in M‐theory, F‐theory, and S‐theory compactifications, all possible complete intersections Calabi‐Yau five‐folds in a product of four or less complex projective spaces are constructed, with up to four constraints. A total of 27 068 spaces are obtained, which are not related by permutations of rows and columns of the ...

Phase diagrams in nonlocal PNJL models constrained by Lattice QCD results
, 2013 Based on lattice QCD-adjusted SU(2) nonlocal Polyakov--Nambu--Jona-Lasinio (PNJL) models, we investigate how the location of the critical endpoint in the QCD phase diagram depends on the strenght of the vector meson coupling, as well as the Polyakov-loop
